# Revision history:
# 1.0.0 : First release
# 1.0.2 : Minor bugfixes.
# 1.1.0 : Prints version in

, more customizable, optionally allows
# fingering to arbitrary sites for use as a web interface to finger,
# supports VirtualHost sites, better error output.
# 1.1.1 : Highlights URLs and email addresses.
# 1.2.0 : Changed email address. Moved script name to $script_link.
# Reads [title], [url], and [img] tags.
# 1.2.1 : [center] and [font] tags added.
# 1.3.0 : (Yes, I went up two minors in one day.) Plain text output from
# the command line.
# 1.3.1 : Added bold, italics, and underlines ([b][u][i][/i][/u][/b])
# Text output gets the witty remark, etc, too.
# 1.3.2 : Added "?format=n" argument to the web interface, and fixed a
# formatting bug with the [center] tag in Opera.
# 1.3.3 : [link] tags spit out URL in non HTML formatted version. Handles
# newlines in [center] tags for Opera. Fixed bug where HTML
# formatting was enabled in the regular finger interface.
# 1.3.4 : Bugfixes to the "&" -> "&" substitution and the URL
# highlighter. Added almost useless debugging facility.
# 1.3.5 : More debugging output, and randomized titles. Debugging can be
# enabled/disabled in the URL.
# 1.3.6 : Added [wittyremark] tag at a user's request. [title] tags on a
# line by themselves have the newline removed, so that 50 random
# titles don't end up with 50 blank lines in the output; this is
# true for [wittyremark], too. Email address auto-URLifying can
# handle addresses with a '.' at the end, for example at the end
# of a sentence. Changed the ending output, and made the credits
# (formerly $script_link and hardcoded) more configurable.
# 1.3.7 : Removed '\r' chars from textmode footer.
# 1.3.8 : Fixes for Lynx text browser.
# 1.3.9 : Allows use of [defaultsection] and [section=""][/section] tags.
# This is hacky right now. DO NOT USE THESE TAGS.
# 1.3.10 : Modified the URL-detecting regexp to be a little more accurate.

# TODO: Let [img] tags nest inside [link] tags.

# land in here, so you are interfering with their ability to override the
# title if you add to this array. The $title variable above is used only if
# this array is empty, and thus gives you a comfortable default in case the
# user doesn't supply her own title. Do as you will.
